Brief Introduction of Solar Cells

A solar cell, is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon. It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are the building blocks of photovoltaic modules, otherwise known as solar panels

Monocrystal solar energy cell

remark:our company cells as per working current concentrate principle,separate the first and the second grade

Applications of Polycrystalline Solar Cells

Assemblies of photovoltaic cells are used to make solar modules which generate electrical power from sunlight, as distinguished from a "solar module" or "solar panel". A solar array generates solar power using solar energy.

How Much Do Solar Panels Cost On My Roof?

When you ask, “How much do solar panels cost?,” what I think you really want to know is how much it costs to put solar panels on your roof, right?

The bulk of the price of going solar is now the “soft costs” (installation, permitting, etc.) rather than the solar panel cost. Referencing the latest US Solar Market Insight report, the average installed cost of a residential solar panel system is approximately $3.50/watt. (For commercial rooftops, it’s approximately $2.00/watt.)

However, prices vary tremendously by region. “Common residential system prices ranged from less than $3.00/W to just above $7.00/W,” the Solar Energy Industries Association wrote in 2014 regarding 2013 figures. The story hasn’t changed much since then, even though prices on both ends have come down.

The total price of a system, of course, varies tremendously based on the size of your roof and your electricity needs as well.

So, the key is really just to get an initial quote and then get a closer look at your situation from a local installer, who can give you a more specific quote.

Decrease the cost of solar cells

Reduce the silicon material production cost will be the most important measure. At present, under the condition of the high price of silicon, silicon material accounted for 70% ~ 80% of the cost, it is the reason about that. Control the cost of the battery production, Reduce consumption equals reduce cost, silicon material shortage bring a deadly blow to the industry, at the same time, also promote technological progress. Thinned wafers is a very important measure for any country to reduce cost or to improve the efficiency. Then, improve the efficiency of the battery .However, the speed of Battery efficiency increases depend on the quality of process equipment, pursuit of efficiency will make the cost increase a lot. As a business perspective, improve the efficiency of battery and cost of equipment should maintain a balance.

Develops equipment potential will be the another choice. We should vigorously carry out technological innovation, develop the high effectively ways on reduce the cost and improve the conversion efficiency of new technology, new material. At the same time we should pay attention to the integration technologies, the development of large-scale production line, to make solar cells more competitive.
